Backfiring on decelleration- electra glide classic
I have a \\;2002 \\;\\electraglide classic with fuel injection- ever since having the cam tensioners replaced while on a trip I immediately started having a problem with the bike excessively backfiring on deceleration and it occasionally pops through the air throttle body. \\; This never happened before having the cam tensioners replaced.The local harley dealer \\;is having a problem coming up with the cause. \\;They've replaced the pipes, tested for exhaust leaks, checked electrical components, done a valve leak down test and a fuel pressure test as well as all the computer diagnostic \\; with all coming up having no problems. \\; Dealership has done all they can do without starting to replace costly parts without a direction as to whats causing the problem....any ideas??

Did the dealer go back into the cam chest and check to make sure that the timing marks are all line up the way they are supposed to be, etc.?

Thanks dawg, would you happen to know if the timing marks are out if it would or could affect just the deceleration problem or would the bike also not run properly on acceleration...right now it operates fine on acceleration..

I was thinking externally, the induction module has many sensors, flanges, injectors, etc. that are sealed by O-rings. \\; If air is leaking through a bad rubber seal or O-ring, it could mess with AFR, and could possibly result in symptoms you describe. \\;
